fuzzer

Fuzzers are widely used tools for testing software. They can generate random test cases and use them as input against the software under fuzzing/testing. Since the tests have randomly-built content, it is not necessary to check them for correctness, but they are suitable for catching rough bugs like use-after-frees, memory corruptions, assertion failures and further crashes. There are many approaches how to generate these tests, but all of them can be categorized into three main groups: whitebox, blackbox and graybox fuzzers.
